Embodiment 1

[0067] A kind of hot and humid comfortable polyester fiber FDY yarn for winter, the preparation method is:

[0068] (1) preparation of oiling agent for oiling;

[0069] Mix 2-hydroxymethyl-12-crown-4 with potassium dodecyl phosphate, trimethylolpropane laurate and sodium hexadecylsulfonate at room temperature and add to 12# mineral oil and uniformly stirred at 40°C for 2.5h to obtain an oil agent; the addition amount of each component is as follows in parts by weight: 5 parts of 12# mineral oil; 95 parts of 2-hydroxymethyl-12-crown-4; 12 9 parts of potassium alkyl phosphate; 2 parts of sodium hexadecyl sulfonate. The content of crown ether in the prepared oil is 85.58wt%. The oil has excellent high temperature resistance. After heat treatment at 200°C for 2 hours, the thermal weight loss is 9wt%. The viscosity of the oil is low. When the kinematic viscosity is 29.5mm 2 / s, the kinematic viscosity after the concentration of 10wt% emulsion is configured with water is 0.93mm ...

Embodiment 2

[0075] A kind of hot and humid comfortable polyester fiber FDY yarn for winter, the preparation method is:

[0076] (1) Preparation of oiling agent for oiling; 15-crown ether-5 and isomeric tridecyl alcohol polyoxyethylene ether phosphate potassium salt, trimethylolpropane laurate and sodium dodecylsulfonate are mixed at room temperature After mixing evenly, add it to 13# mineral oil and stir evenly at 52°C for 2 hours to obtain an oil agent; in parts by weight, the addition amount of each component is as follows: 10 parts of 13# mineral oil; trimethylolpropane lauric acid 5 parts of ester; 70 parts of 15-crown ether-5; 8 parts of isomeric tridecyl polyoxyethylene ether phosphate potassium salt; 6 parts of sodium dodecylsulfonate. The content of the crown ether in the prepared oil is 70.70wt%. The high temperature resistance of the oil is excellent. After heat treatment at 200°C for 2 hours, the thermal weight loss is 13.5wt%. The viscosity of the oil is low, at (50 ± 0.01) A...

Embodiment 3

[0082] A kind of hot and humid comfortable polyester fiber FDY yarn for winter, the preparation method is:

[0083] (1) Oil preparation for oiling; 2-hydroxymethyl-15-crown-5 and potassium salt of tetradecyl phosphate, trimethylolpropane laurate and sodium pentadecylsulfonate After mixing evenly at room temperature, add it to 11# mineral oil and stir evenly at 48°C for 3 hours to obtain an oil agent; in parts by weight, the addition amount of each component is as follows: 8 parts of 11# mineral oil; trimethylolpropane lauryl 10 parts of acid ester;

[0084] 2-Hydroxymethyl-15-crown-585 parts; Tetradecyl phosphate potassium salt 11 parts; Sodium pentadecylsulfonate 5 parts. The content of crown ether in the prepared oil is 70.83wt%. The oil has excellent high temperature resistance. After heat treatment at 200°C for 2 hours, the thermal weight loss is 11wt%. The viscosity of the oil is low. When the kinematic viscosity is 30.1mm 2 / s, the kinematic viscosity after the concen...

Abstract

The invention relates to a hot and humid and comfortable polyester fiber FDY silk for winter and a preparation method thereof. The preparation method comprises the following steps that the hot and humid and comfortable polyester fiber FDY silk for winter is prepared by conducting weighing, extrusion by a composite spinneret plate, cooling, oiling, stretching, heat shaping and winding on a spinningmelt, the texture of the silk is polyester with a matte agent being dispersed, the thermal resistance of the obtained woven fabric is higher than or equal to 0.18m<2>. DEG C / W, the moisture vapor resistance of the woven fabric is lower than or equal to 14 Pa.m<2> / W, cross-shaped spinneret orifices and double-cross-shaped spinneret orifices are formed in the composite spinneret plate simultaneously, the micropore length ratio of the cross-shaped spinneret orifices and the double-cross-shaped spinneret orifices is equal to product of the equivalent diameter ratio and the coefficient K, the value range of the coefficient K is between 0.97 and 1.03, an oiling agent used in the oiling contains crown ether, and the content of crown ether is 67.30-85.58wt%. The preparation method is simple, theobtained polyester fiber FDY is excellent in thermal-wet comfort, and has considerable application prospects.

Description

technical field [0001] The invention belongs to the field of fiber preparation, and relates to a winter hot and humid comfortable polyester fiber FDY and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, people's requirements for fabrics are getting higher and higher. While pursuing fashionable and elegant clothing, they also require clothing to be comfortable to wear. Comfort means that fabrics can meet people's physiological needs when they are in contact with people in the wearing environment. , Heart needs, the most important thing about fabric comfort is heat and humidity comfort, heat and humidity comfort refers to the fabric maintains a constant body temperature between the heat and moisture transfer between people and the environment, and creates good conditions for the normal physiological functions of the human body, so that The human body maintains a sense of comfort. The heat and humidity comfort of cl...
